A 100V battery is connected to a 100 micro-Farad capacitor. The stored energy is given by U=1/2C(delta V)^2. Which is 0.5J. The battery is taken out of the circuit and the capacitor is connected to another 100 micro-Farad capacitor. Using the same equation above and considering the potential difference for each capacitor is then 50V you get .125J for each capacitor. We were told to assume there was no electrical resistance in this circuit. My question is...were did the .25J of energy dissappear to? Thanks for the help!
